Cutting Blade Assembly for Leather Skiving Machines

Product Specifications

Technical details and manufacturing context for Cutting Blade Assembly

Definition

The cutting blade assembly is a critical component of an industrial leather skiving machine, responsible for precisely shaving leather to achieve uniform thickness. It consists of the cutting blade, blade holder, adjustment mechanisms, and mounting hardware, designed to maintain consistent cutting depth and angle during high-speed skiving operations. The assembly is available in configurations with blade widths from 50 to 150 mm, blade thicknesses from 0.5 to 1.2 mm, and cutting angles from 15 to 30 degrees. Blade hardness ranges from 58 to 62 HRC, and the blade material is specified as Cr12MoV high-carbon chromium steel, referencing standard GB/T 1299. Mounting hole diameters range from 8 to 20 mm, and blade runout is maintained at or below 0.02 mm to ensure uniform skiving thickness. The maximum operating speed is 3000 to 6000 rpm, and the operating temperature range is -10 to 60 degrees Celsius. The assembly weighs between 0.5 and 2.5 kg. These parameters serve as reference ranges for selection and must be verified against the specific machine model and application. The assembly is designed for use in leather and related product manufacturing, where it is mounted onto the skiving machine spindle. Proper installation and alignment are essential for optimal performance. Regular inspection of blade wear and adjustment mechanisms is recommended to maintain cutting quality. Always consult the legal manufacturer or supplier to confirm model-specific values and standards before procurement or use.

Working Principle

The assembly holds the cutting blade at a precise angle relative to the leather surface. As leather passes through the machine, the blade removes a thin, consistent layer from the underside. The assembly allows for micro-adjustments to control cutting depth and maintains blade stability during operation. The blade's cutting angle and depth are set via adjustment mechanisms, and the mounting hardware ensures secure attachment to the machine spindle. During operation, the blade rotates at speeds up to 6000 rpm, and the runout is kept within 0.02 mm to avoid vibration and ensure a clean cut. The operator must set the cutting depth according to the desired leather thickness, and the assembly's stability is critical for uniform results.

Frequently Asked Questions

What materials are used for the cutting blade?

The blade material is specified as Cr12MoV high-carbon chromium steel, referencing standard GB/T 1299. Other materials such as high-speed steel, tungsten carbide, and stainless steel may be available depending on the model, but the listed standard is a reference for verification.

What is the maximum operating speed?

The maximum operating speed is 3000 to 6000 rpm. Exceeding this range may cause vibration and poor cut quality. Always confirm the speed rating for your specific assembly model.

How do I ensure uniform skiving thickness?

Uniform thickness depends on maintaining blade runout at or below 0.02 mm and proper adjustment of cutting depth and angle. Regular inspection and calibration of the assembly are recommended.

What are the operating temperature limits?

The operating temperature range is -10 to 60 degrees Celsius. Operating outside this range may affect blade material properties and performance. Verify with the manufacturer for your application.
